So I had been dating this guy for over a year, we seemed to be getting along just great. He talked about all the fun stuff we're going to do, and how he loves spending time together, exc. Over the summer, we started arguing a lot, and called each other to figure out what to do, if we needed to take a break or not. We ended up agreeing that we're just stressed, and we'd work it out. So for the next two months we were great, no arguing at all. He had a week long church camp come up where you can't bring your phone, so we saw each other two days before he left, and we hugged and kissed and said how much we were going to miss each other. The week went by, and the day he got back, he tried breaking up over text. I called him asking what was happening, and he gave me vague reasons as to why he was breaking up so spontaneously. To this day he can't tell me exactly why. Then, I found out that he started dating another girl younger than, and who's family has done drugs and stuff, only about two weeks after we broke up. I know she goes to the same church as him and probably went to the camp with him. And getting into a relationship with someone only two weeks after breaking up with someone who he had dated for over a year seems incredibly fast. I think he broke up with me so he could date her, since she's more of the drug party type, and he's always liked doing stupid stuff too, while I've always been the "goody-two shoes" of the friend group. I just want other people's opinion on why he might have randomly broken up with barely any reasons, and is dating someone else so fast and immature. Thanks for reading!!
